OBJECTIVE To investigate the epidemiological characteristics,clinical features and distribution of pathogens isolated from the burn wound patients with infections in a northwestern hospital from 2014 to 2023 so as to provide bases for prevention and treatment of burn wound infections in the northwestern region.METHODS The epidemiological characteristics,clinical features and distribution of pathogenic isolated from the burn wound patients with infections who were treated in the 940th Hospital of Joint Logistic Support Force from 2014 to 2023 were retrospectively analyzed.RESULTS A total of 2122 burn wound patients were enrolled in the study,397(18.71％)of whom had infections,including 306(14.42％)patients with community-acquired infections and 91(4.29％)patients with hospital-acquired infections.The proportion infections was higher among the patients aged no less than 60 years old(63/154)than among the patients aged less than 14 years old(231/983)and the pa-tients aged between 14 and 60 years old(103/985)(x2=108.840,P＜0.001).The proportion of infections was higher among the patients with the burn wound depth no less than grade Ⅲ(146/458)than among the patients with the burn wound depth no less than grade Ⅱ(251/1664)(x2=66.600,P＜0.001).The proportion infections was higher among the patients with burn wounds in limbs(370/1881)than among the patients with burn wounds in other sites(1153/1987)(x2=47.244,P＜0.001).The isolation rates of methicillin-resistant Staphy-lococcus epidermidis and carbapenem-resistant Pseudomonas aeruginosa strains showed downward trends from 2014 to 2023,the isolation rates of carbapenem-resistant Klebsiella pneumoniae and the third generation cephalo-sporins-resistant Escherichia coli showed upward trends,however,there were no significant differences.CONCLUSIONS The patients with no less than 60 years of age,no lower than grade Ⅲ of burn wound depth and burn wounds in limbs are more likely to have burn wound infections.S.aureus is the predominant species of pathogens causing the infections.The isolation rates of carbapenem-resistant K.pneumoniae strains and the third generation cephalosporins-resistant E.coli strains show upward trends.It is necessary to take targeted prevention and treatment measures for the burn wound infections.

Objective:To analysis effectiveness of the "14 plus 7 day quarantine" and "nucleic acid plus total antibody testing" strategy (combined screening strategy) for screenin the imported patients with COVID-19 in Xiamen.Methods:The study populations were overseas travelers arriving in Xiamen from March 17 to December 31, 2020, and overseas travelers who had quarantine outside Xiamen for less than 21 days from July 18 to December 31, 2020. Data were collected and analyzed on the timing of detection, pathways, and test results of the imported patients with COVID-19 after implementing combined screening strategy.Results:A total of 304 imported patients with COVID-19 were found from 174 628 overseas travelers and 943 overseas travelers from other cities. A total of 163 cases (53.6%) were diagnosed by multitime, multisite intensive nucleic acid testing after positive finding in total antibody testing. Among them, 27 (8.9%) were first positive for nucleic acid in 14 plus 7 day quarantine and 136 were first positive for nucleic acid in 14-day quarantine. Only 8 of these individuals were tested positive for nucleic acid after positive total antibody testing. The other 128 individuals were tested positive for nucleic acid after being negative for average 2.3 times (maximum of 6 times). Aditional 155 cases might be detected by using the combined "14 plus 7 day quarantine" and " nucleic acid plus total antibody testing" strategy compared with "14-day quarantine and nucleic acid testing" strategy, accounting for 51.0% of the total inbound infections. So the combined screening strategy doubled the detection rate for imported patients with COVID-19. No second-generation case caused by overseas travelers had been reported in Xiamen as of February 26, 2021.Conclusions:Xiamen's combined screening strategy can effectively screen the imported patients with COVID-19 who were first positive for nucleic acid after 14 day quarantine. Compared with "14 day quarantine and nucleic acid testing", the combined screening strategy improved detection rate and further reduced the risk of the secondary transmission caused by the imported patients with COVID-19.

Objective To construct clinical nursing teaching evaluation index based on nursing teaching and student′s subjective evaluation. Methods The clinical nursing teaching effect evaluation index were evaluated which primarily constructed by the application of analytic hierarchy process. Results For the judgment of evaluation results, we obtained 19 experts evaluation results after picking out 3 experts′ results because of consistency evaluation ( CR≥0. 1 ) . To summarize each experts′ score, there were 4 dimensions including clinical teaching content, clinical teaching method, clinical teacher′s practice ability and teaching effects, 12 secondary indexes, 25 tertiary indexes to settle weight. Conclusions The clinical nursing teaching effect evaluation index is primarily constructed including 4 dimensions, 12 secondary indexes and 25 tertiary indexes.
